This adds definitions for the OV32 and CA32 bits of XER that were introduced in POWER ISA v3.0. There are some existing instructions that currently set the OV and CA bits based on certain conditions. The emulation behaviour of all these instructions needs to be updated to set these new bits accordingly.
